WATER-FILTER.

SPECIFICATION forming part of Letters Patent No. 632,339, dated September 5, 1899.

Application filed November 25,1898. Serial No. 697,347. (No model.)

To all whom it may concern.-

Be it known that we, CORNELIUS B. DAR- LING, ROLLA R. DARL NG, and WILLIAM T. MANN, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Water-Filters; and we do declare that the following is a full,clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to water-filters; and the invention consists in a water-filter which is especially adapted to domestic uses and which by reason ofits simplicity of construction is easily handled for cleansing and is comparatively cheap as an article of manufacture and sale.

To these several ends the invention is comprised in a filter, substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of our improved filter. Fig. 2 is a vertical central sectional elevation thereof. Fig. 3 is a perspective of the stem or nipple which occupies the plugged end of the filtering-tube. Fig. 4 shows a filtering-tube detached from the filter and a compressible bulb connected thereto to exert a counterpressure through the tube and clear it of accumulated impurities.

A represents the outer casing of the filter, having a removable bottom B, which is in the form of a cap and is threaded onto the body, so as to be easily detached for the removal of tho filtering-tube C. At its top the casing or body A has an internally-threaded neck 2, adapted to screw onto a sink or other faucet, and gaskets are employed, as usual, at both ends to prevent leakage. The body A not being over about five inches in length and, say, two inches through its center, the milled edge 3 of cap 13 answers every purpose of a hand-grip to detach and attach said cap, and of course the grip on the body of the filter suffices to screw it on and remove it from the faucet.

The filter-tube C may be of natural stone or manufactured after the manner of any of the well-known artificial filtering-tubes and may be more or less porous, according to place of use, the character of the water, or other conditions, but usuallya tube of medium porosity and which will intercept microbes and cleanse 5 5 the water of all or practically all removable impurities is the kind of tube that should be used. Such tubes are available and entirely practicable with the ordinary water-pressures of our large cities. The tube Cas here shown has a fair degree of thickness, though it is supposed to be a manufactured and not a natural stone tube, and its otherwise open and lower end is closed by a plug D, of suitable materialsay some kind of firm cement or substance which will fasten itself perma nently to the side of the tube and serve also as a support for the discharge-nipple or tubular stem E, projecting through the same.

This nipple or stem preferably is flared at its jecting from the tube C, substantially as shown, the said stem serves two important functions and contributes very materially to the merits of the filter both as to its operativeness and economy of manufacture and sale.

It will be noticed that the bottom cap B has a'central neck 5 with a passage through the same, and this passage corresponds so nearly to the size of the stem or nipple E that a slight and ordinary piece of rubber tubing G removably slipped onto the nipple E and extending 0 out through the neck 5 serves to pack the sleeve water-tight in the said neck and passage and make it perfectly water-tight against the pressure within as well as affording a conduit for the filtered water to the consumer.

Then, again, the stem or nipple E becomes the sole medium of support for the filter-tube, acting as a standard on which it rests. The bottom cap B and the filter-tube are thus so connected mechanically and operatively that they are removable and replaceable togeth er-- that is, when they are removed together and This kind of fastening is pro- 75 separated for cleansing the tube 0 they are again united before restoring to place-and the nipple or stem E extends into the passage through said cap far enough to make a secure engagement therein. Then when cleansing is necessary by reason of more or less deposit on the surface of the filter and some penetration possibly of its pores We find it convenient to simply attach a rubber bulb H or like means and by atmospheric pressure forcing the water in tube 0 out through its sides and end, and thus effectually cleansing it and fitting the tube for further use. Of course other methods of cleansing will suggest themselves and may be employed, but this is a simple and efiective Way.

If at any time the tube 0 should by accident be broken or for any reason become defective and require replacement, the complete article would consist of the tube 0 and its nipple or tubular stem E and with or Without the rubber tubing G, constituting conduit and packing, as hereinbefore described. This tubing G can be gotten at any store Where an assortment of rubber goods is kept, and it may have greater length than here shown, if preferred.

The flow of the water is cut ofi in the faucet or cook to which the filter is attached, and this will be understood in connection with the use of the filter.

What We claim is- 1. The casing having an outlet at one end and a filter-tube having a tubular supportingstem in said outlet, and a flexible dischargetube sleeved over said stem and extending through said outlet, substantially as described.

v 2. The filtering-tube having a plugged end and the tubular stem secured in the said plug and a flexible ring in the plug engaging said stem, substantially as described.

3. The filtering-tube and the nipple projecting through one end thereof and constructed to sleeve a flexible tube over the same, in combination with a flexible tube on said nipple, substantially as described.

l. The filtercasing and the filter tube therein, a tubular stem supporting said tube in the filter-casing and a flexible tube engaged over said stem and extending through to the outside of the filter-casing and serving as a conduit for the filtered Water, substantially as described.

Vitness our hands to the foregoing specification this 28th day of September, 1898.
